In this paper we will focus on the problem of removing speckle in 3D ultrasound (US) images while maintaining the structure information unaltered. It is intended as a preprocessing step for further image analysis modules. Optimum Wiener filter technique will be used but modified in two senses: first, Rice distribution will be used prior to applying the Wiener filter to correct for the bias which may...
A new and complementary method to assess image quality is presented. It is based on the comparison of the local variance distribution of two images. This new quality index is better suited to assess the non-stationarity of images, therefore it explicitly focuses on the image structure. We show that this new index outperforms other methods for the assessment of image quality in medical images
